This 71-year-old retired bailiff and former New York cop should've gnome better.

Robert Willmarth, 71, of Jensen Beach, is accused of hurling a cement gnome statue through a neighbor’s window and is also a suspected of setting fires to homes and cars in his own neighborhood, reports The Palm Beach Post.

After detectived showed Willmarth a surveillance video of him throwing the garden gnome into a window of his neighbor’s home while they were away on vacation, he allegedly told them he did it because the neighbor had "just busted my chops the other day," according to the report.

It sounds like he needed some chop busting.

It's also not the first time somebody used a garden gnome to committ a crime.
